T o all whom t my concern:

Be it known that I, ARTHUR LovELL, a

citizen of the United States, residing at Douthat, in the county of Ottawa and State of Oklahoma, have invented certain new and useful Improvements in Roofing-Tiles, of which the following is a specification.

-This invention relates to tiles used as roofing for dwelling houses and other similar places; and it consists in the novel construction of the tile and the method of making it as hereinafter fully described and claimed.

In the drawings, Figure l is a front view of a. tile constructed according to this invention with a portion of the metal sheet broken away to expose the felt. Fig. 2 is a cross-section through a portion of the tile drawn to an enlarged size.

The tile is provided with ua body portion 2 formed of roofing felt impregnated with asphalt, and if desired one surface of it may have additional asphalt applied to it. This body portion is faced with a thin sheet 3 of metallic Zinc. The felt is cut into tiles or plates of the same size and shape as the tiles preferred for use in roofing. This is done before having the Zinc applied to it. The zinc is rolled out very thin, and is cut into similar plates. ,The zinc facing plates are heated in a suitable oven or furnace to a heat sufficient to liquefy asphalt. The heated Zinc plates are then placed on the asphalt coated sheets of felt, and pressure is applied t them while het by means of a suitable press or other machine, so that the asphalt is melted and the zinc facing plates are forced into intimate contact with the felt, all air being forced out and excluded.

The facing plates are caused to adhere tightly to the felt, and the felt is compressed and consolidated. The edges of the tiles are subsequently trimmed if necessary by any suitable cutting machine or shears.

The press which unites the zinc facing plates to the felt may also be caused to indent the tiles so that they receive suitable surface ornamentation, as is usual with roofing tiles, and so as to cause the zinc to a'dhere more closely to the felt. The metal zinc is used on account of it not oxidizing quickly, and as it is relatively inexpensive, and able to be rolled into suiiiciently thin and stiff plates without breaking. The felt impregnated with the asphalt is consolidated by being compressed when the hot zinc plate is applied to one surface of it, and which only melts the asphalt with which it is pressed in contact. One exposed surface of the tile is formed by the metal Zinc which does not readily oxidize, and its other exposed surface is formed by the compressed felt and asphalt. Tiles constructed of these specific materials, and separately by the method hereinbefore set forth, are found to be a superior covering for roofs, and are relatively light in weight and are inexpensive to manufacture.

What I claim is:

l. A roofing tile, comprising a sheet or body portion of compressed felt impregnated with asphalt, and a facing plate of metallic sheet Zinc permanently secured to one asphalted side surface of the felt body portion, one exposed surface of the, tile being formed by the sheet zinc and its other exposed surface being formed by the compressed felt.

2. A method of forming a roofing tile, which consists in pressing a thin sheet of zinc while hot into intimate Contact with a sheet of felt impregnated with asphalt, the zinc sheet being heated to a temperature suicient to liquefy the asphalt, and both felt and zinc having been cut to a suitable size and shape to form the tile before being pressed together.

In testimony whereof I have aiiixed my signature.

ARTHUR LOVELL.
